SUMMARY OF THE INVENTION

The present invention discloses a lifting mechanism for a seat of a toilet, where at least part of the mechanism may be concealed. The lifting mechanism may enable maintaining the toilet seat in a lifted position, where the seat is adjacent to the cover of the toilet and substantially perpendicular to the rim of the toilet bowl, for the improved comfort, convenience, and hygiene of a user.

According to embodiments of the invention, the lifting mechanism may comprise at least one of: (i) toilet seat holders connected to the hack interior parts of the seat and bowl of the toilet enabling to maintain the seat in a lifted position as long as no substantial weight is applied upon the seat (e.g. the user's body weight when sitting upon the seat); (ii) delay mechanism enabling to delay and slow down the momentum of the lifting of the seat.

According to some embodiments of the invention, the lifting mechanism may comprise a holder enabling to lift the seat, where the holder may comprise:

-   -   a curved upper portion that enables fastening to said seat;     -   a lower portion that enables fastening to said bowl; and     -   a torsion spring threaded to the top edge of the upper portion,         wherein the edges of said spring are protruding enabling to be         fastened to the upper portion's cross section at one edge and to         the inner side of the seat at the other edge.

According to some embodiments of the invention, the holder may enable lifting the seat and maintaining the seat in a lifted position, in which the seat is substantially perpendicular to the rim of the bowl, when no force is applied by a user to push said seat towards said rim, where the fastening of the spring's edge to the seat may enable concealing of said spring in said seat.

According to some embodiments of the invention, the holder may be substantially concealed in the inner side of the seat. The inner side of the seat may comprise at least one niche and at least one slit enabling the coil of said spring to be seated in said niche and the protruding edge of said spring to be seated in said slit. The upper portion of the holder may comprise a slit, enabling the other protruding edge of the spring to slide into the slit of said upper portion. The mechanism lower portion of the holder may enable connecting the bowl and the scat by threading into a hole carved at the bowl. In that way, the spring may be held compressed and hidden between the inner side of the seat and the bowl.

The holder may maintain the spring in a compressed position enabling the spring to maintain the lifted position, where upon applying force in order to lower the seat, the spring may be further compressed enabling to automatically return the seat to the lifted position by returning to the former position of the spring when the force is no longer applied.

According to some embodiments of the invention, the lifting mechanism may further comprise at least one delay member attached to the bottom side of the toilet seat. The delay members may enable delaying the momentum of the seat when automatically lifted upwards by the holders. The delay members may be vacuum knobs, which comprise cavities enabling to empty when pressure is applied upon them. Once the user applies force that pushes the seat against the bowl, the cavity inside the knobs may be emptied of air allowing the knobs to stick to the bowl's rim. Once the seat is lifted, the attaching of the knobs may enable delaying the lift throughout a time-interval by applying an attaching force, which may counteract the lifting force applied by the holder, until the knobs are detached from the rim of the bowl.

Additionally, according to some embodiments of the invention, the lifting mechanism may further comprise at least one shock absorber made from shock absorbing materials such as rubber, where the absorbers may be attached to the inner side of the toilet's cover to enable softening of the contact impact between the seat and the cover once the seat is lifted to the lifted position.

According to some embodiments of the invention, the holder may comprise at least two discs coaxially and adjacently threaded through the holder's upper portion rod. Each surface of each disc that faces the other disc may comprise a protrusion enabling the discs to block the holder's rotational movement when the seat is lifted, where the discs' protrusions location and size may be predefined to prevent the seat from further lilting from a predefined blocking point on.

Alternatively, according to some embodiments of the invention, the discs may not comprise a protrusion but the thickness of the encircling circumference of each disc may be un-uniform, where upon lifting of the seat the average distance between the discs diminishes up to a predefined point where the discs prevent the seat from further lifting.

Additionally, once the toilet cover is lowered to a closed position in which the cover and the seat are substantially adjacent and cover the bowl, the weight of the cover may enable overcoming the lifting force of the holder, enabling to maintain the closed position. The weight of the cover may be predefined to allow fulfilling this function.

FIG. 2A and FIG. 2B schematically illustrate a concealed toilet scat 106 holder 200, according to some embodiments of the invention. The holder 200 may connect the toilet seat 106 to the toilet bowl 104 as illustrated in FIG. 3A. The holder 200 may enable to maintain the toilet seat 106 in a lifted position, where the lifted position is where the cover 108 and the seat 106 are opened an substantially perpendicular to one another, as illustrated in FIG. 1.

According to some embodiments if the invention, the toilet seat holder 200 may comprise:

-   -   an upper portion 22 which may be a curved rod;     -   a lower portion 44, which may be threaded to enable fastening         the holder 200 to the toilet bowl 104 and/or to the seat 106;         and     -   a coiled spring 204 that may be a torsion spring that may be         threaded to the edge of the upper portion 22 to allow the         tension of the spring 204 to maintain the seat 106 in a lifted         position unless a substantial weight (such as the user's body         weight) enables lowering it.

According to some embodiments of the invention, as illustrated in FIGS. 2A and 2B, the upper portion 22 may be connected to the lower portion 44 through a connector 202. The lower part of the upper portion 22 may be shifted from the center of the connector 202 (non-concentric) to allow connecting the upper portion 22 to predefined connecting points positioned at a predefined distance from one another in the seat 106 and the lower portion 44 to fastening parts enabling to fasten to the lower portion 44 edges, where the parts may be positioned at a predefined distance from one another that is different from the distance between the seat's 106 parts.

Alternatively, the upper portion 22 and the lower portion 44 may be jointly configured as a single piece (e.g. a single rod threaded at its tower portion 44 and curved as a hook or an angle at its upper portion 22).

According to some embodiments of the invention, as illustrated in FIG. 2A and FIG. 2B, the spring's 204 edges 205 may be protruding out of the coil to allow one edge 205 to slide into a slit 210 carved at the front cross section of the upper portion 22 of the holder 200 and the other edge 205 to slide into a track slit 409 carved at the interior side of the seat 106, as illustrated in FIG. 3B.

According to some embodiments of the invention, the threaded parts of the tower portions 44 may be threaded through holes drilled at the bowl 104 (as usually is the case in many toilet bowls 104). Each lower portion 44 may be fastened to the bowl 104 by fastening means 208 known in the art, as illustrated in FIG. 3A. The inner part of the seat 106 may comprise carved niches 408 designed to fit the circumference of the springs 204 to be seated inside the niches 408 and each protruding edge 205 to be seated in a connected slit 409 connected to each niche 408, as illustrated in FIG. 3B. By inserting the coiled springs 204 into the niches 408, the holders 200 may be effectively concealed from plain view enabling to conceal the holders 200. The concealment may facilitate in increasing the esthetic value of the toilet seat 106.

Accordingly, each holder 200 may be held fastened to the seat 106 at one end and to the bowl 104 at the other, allowing to hold the seat 106 and the bowl 104 connected. The springs 204 may be held in a compressed position where the applying of a force to lower the seat 106 (e.g. the weight of the user) may pull the strings 106 to a more compressed state enabling the strain of the compressed strings 106 to carry out the lifting of the seat 106 by relaxing back to their former position.

According to some embodiments of the invention, as illustrated in FIG. 4, at least one delay member 20 may be attached to the seat 106 enabling to delay and slow down the momentum of the seat 106 when automatically lifted upwards by the holders 200. The delay members 20 may be, for example, vacuum knobs attached to the bottom side of the seat 106 where in a sitting position, when the user applies weight upon the seat 106, the delay members 20 may be attached to the upper circumference rite of the bowl 104, where the cavity of the knob may be emptied of air allowing the delay member 20 to stick to the rim. Once the user gets up and off of the seat 106, the holders 200 may apply force to allow lifting of the seat 106 back up, where the delay members 20 may apply temporary counteracting force, by clinging to the rim of the bowl 104 enabling to delay and slow down the lifting until the delay members 20 are detached from the bowl 104 (and hence can no longer apply the counteracting delay force).

Additionally, the delay time-interval, which is an average time it take from the moment the seat 106 is lifted until the knob delay member 20 is detached from the bowl 104 rim may be predefined by the shape, depth and/or volume of the cavity inside the knob, for example. The time-interval may be defined in relation to the physical dimensions of the knob's cavity enabling to select a knob of specific dimensions according to desirable time-intervals.

Alternatively, the delay members 20 may be made from flexible materials that have a substantial relaxation time-interval so that the delay members 20 may be compressed when the user's weight is applied upon the seat 106 pushing the delay members 20 against the rim of the bowl 104 and decompressed slowly relaxing back to their stretched position until the delay members 20 can detach from the rim in a substantially full relaxed position.

Additionally, according to some embodiments of the invention, at least one shock absorber 50 may be attached to the inner side of the cover 108 to facilitate in absorbing and softening the contact impact between this side of the cover 108 and the seat 106 when the seat 106 is lifted upwards and reaches the lifted position. The absorbers 50 may be made from absorbing materials such as sponge like elastic polyesters and the like, as known in the art and may be attached to the inner side of the cover 108 that meets the seat 106 in a lifted position of the seat 106.

Additionally, according to some embodiments of the invention, the material from which the cover 108 is made may be selected to allow the assembly of the seat 106 and the cover 108 to maintain in a lowered position, as illustrated in FIG. 5B, when the user lowers the cover 108 and the seat 106 to the lowered position. This may mean that the weight of the cover 108, pushing towards the floor (due to the gravity force that the weight may apply) may be substantial enough to resist or counteract the lifting force applied by the holders 200 and maintain the assembly in the lowered closed position.

According to some embodiments of the invention, as illustrated in FIG. 1. FIG. 3A and FIG. 4, the lifting mechanism may comprise two holders 200 fastened to the bowl 108 and seat 106.

FIGS. 6-7 schematically illustrate a blocking mechanism, according to some embodiments of the invention. The blocking mechanism may comprise at least two discs 220A and 220B that may be coaxially and adjacently threaded through the holder's 200 rod of the upper portion 22. The discs 220 may be designed to enable blocking of the seat's 106 rotational movement that enables the lilting of the seat 106 to prevent the seat 106 from hitting the cover 108 or even come in contact with the cover 108 when lifted.

According to some embodiments of the invention, as illustrated in FIG. 6, the thickness of the encircling circumference of each disc 220 may be un-uniform (e.g. gradually growing from one point upon the circumference onwards). Upon automatic lifting of the seat 106 the average distance between the discs 220A and 220B may diminish up to a predefined point where the discs prevent the holder 200 from further rotating and hence prevent the seat 106 from further lilting. This point may be predefined in the mechanism defining the aperture between the seat 106 and the bowl 104 in the lifted position.

According to some embodiments of the invention, as illustrated in FIG. 7, each surface of each disc 220 that faces the other disc 220 may comprise a protrusion 221A and 221B enabling the discs 220A and 220B to block the holder's 200 rotational movement when lifting the seat 106. The protrusions 221A and 221B location and size may be predefined to prevent the seat 106 from further lifting from a predefined blocking point on, for example, to prevent the seat 106 from reaching and touching the cover 108 when lifted to the maximal aperture of the lifted position.

Additionally, adjusting means 225 may be added to the discs 220, as illustrated in FIG. 8, to allow adjusting the position in which the seat 106 may be blocked from liking by, for example, attaching the discs 220A and 220B therefore increasing the friction between them. For example, at least one screw button as the adjusting means 225 threaded through the discs 220A and 220B and through the seat 106 and cover 108 enabling the user to secure the screw, for example, or loosen it according to the desirable friction between the discs 220A and 220B and the desirable maximal aperture angle between the seat 106 and cover 108. The user may define the aperture of the toilet seat 106 in the lifted position by enabling to tighten the discs 220 to one another by securing the adjusting means 225.

According to some embodiments of the invention, the lifting mechanism may enable removing the seat 106, the cover 108 or both from one another and/or from the bowl 104 to facilitate the user in cleaning the assembly of seat 106 and cover 108 and the bowl 104.

According to some embodiments of the invention the adjusting means 225 may additionally connect the cover 108 the discs 220 and the seat 106 to one another.
